New Nursery School Building in the District Les Sablons, Le Mans, France
This single story 11,840 ft² nursery school accommodates up to 70 children. The building property is also surrounded by playgrounds and other green spaces.

The local political desire was to use sustainable materials for the new building. The district residents voted for a green roof to be included in the project.
The engineering office ARTEMIS INGENIEUR assisted the project management team in the building design phases including preliminary design, final design, project planning, and construction documents. ARTEMIS INGENIEUR designed the structure including the lateral bracing and sizing of the building elements.
The exterior facades consist of timber panel walls. The interior load bearing walls are designed with CLT panels.
The framework includes double glued-laminated tapered beams which supports the green roof and multiple photovoltaic panels.
The structure was analyzed for ULS, SLS, and earthquake (low level of seismicity). The RF-DYNAM Pro add-on module for RFEM was used to perform a modal analysis and generate of equivalent seismic loads.

When designing many members in one design case, it is sometimes difficult to recognize the governing designs. To improve the overview and to display the relevant designs in a compact way, you can use the filter options under the result tables. These are included in all design modules of steel, aluminum and timber structures in RFEM and RSTAB.

RFEM/RSTAB add-on module RF-/JOINTS Timber-Timber to Timber | Design of direct timber connections according to Eurocode 5

The cross-section resistance design analyzes tension and compression along the grain, bending, bending and tension/compression as well as the strength in shear due to shear force.
The design of structural components at risk of buckling or lateral-torsional buckling is performed according to the Equivalent Member Method and considers the systematic axial compression, bending with and without compressive force as well as bending and tension. Deflection of inner spans and cantilevers is compared to the maximal allowable deflection.
Separate design cases allow for a flexible and stability analysis of members, sets of members, and loads.
Design-relevant parameters such as the stability analysis type, member slendernesses, and limit deflections can be freely adjusted.
- In RF-/TIMBER AWC and RF-/TIMBER CSA, I receive the error that says torsion limit exceeded. How do I bypass this error message?
- Why is the strength always reduced by the kmod value of 0.6 during the calculation in the RF‑LAMINATE add‑on module, although I have load combinations with variable loads?
- Can I consider a reduction of the stiffness according to the German regulation NCI NA.5.9 in TIMBER Pro?
- I have selected all available members for design in RF-/TIMBER Pro. Why are tapered members not designed?
- When performing the fire resistance design with TIMBER Pro, I get the error 10001. How can I fix the error?
- Is it possible to set user-defined values when viewing solid stress results?
- How are the signs for the release results of a line release and line hinges interpreted?
- How can I create a curved or arched section?
- Is it possible to design the support pressure or the compression perpendicular to the grain in RX‑TIMBER?
- After the design with RF‑/TIMBER Pro, I optimized a cross-section. Why is the utilization of the optimized cross-section exceeded now?
